Example
The following example shows how to configure the frame length transmitted as 256 cells for IMA group
0/0/ima1:
SwitchA(config)# interface atm 0/0/ima1
SwitchA(config-if)# ima frame-length 256
Displaying the IMA Group Frame Length Configuration
To display the IMA group frame length configuration, use the following EXEC command:
Command
show ima interface [atm card/subcard/imagroup
[detailed]]
Example
The following example shows the IMA group frame length configuration:
SwitchA# show ima interface
ATM0/0/ima1 is up

Configuring IMA Group Test Pattern
An IMA group can have a test pattern defined to provide extra support to verify the connectivity of links
within an IMA group. It uses a test pattern sent over one link to verify connectivity to the rest of the
group. The test pattern should be looped over all the other links in the group at the far end of the
connection. The test procedure is performed using the ICP cells exchanged between both ends of the
IMA virtual links.
To configure the test pattern to be transmitted on the IMA group, perform the following steps, beginning
in global configuration mode:
Command
Step 1
Switch(config)# interface atm card/subcard/imagroup
Switch(config-if)#
